1. COOLING OPERATION
1-1 COOLING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation frequency of the compressor.
* If the room temperature is 2 C higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is 2.5 C lower than a set temperature, the compressor will be
stopped.
* When the room temperature is between +2 C to -2.5 C of the setting temperature,
the compressor frequency is controlled within the range shown in Table1.
However, the maximum frequency is limited in the range shown in Figure 1 based on the
fan speed mode and the outdoor temperature.

( Table 1 : Compressor Frequency Range )
( Fig. 1 : Limit of Maximum Frequency based on Outdoor Temperature )
When the compressor operates for 30 minutes continuously at over the maximum frequency ,
the maximum frequency is changed from Maximum Frequency to Maximum Frequency .
The room temperature is controlled 1 C lower than the setting temperature for 40 minutes
after starting the operation.
After 40 minutes, it is controlled based on the normal setting temperature.
